EMC ECC processes

Does anyone see many entries(more than 60 entries)of ECC's mhragent process attached in the shared memory region and marked as D-rw------- Wonder why?

I'm not 100% sure what your seeing.

On my HPUX box the mhgragent process only shows as one entry (ps -ef | grep ecc)

I check what semaphores it's holding on to with (ipcs -a | grep 0x45), since 0x45 is the address that ECC processes map to. It shows about 6 entries for this shop, not 60.

And the D-rw----- looks like file permissions, whereas in checking memory using ipcs it reflects --ra-ra-ra-.

Don't know if this helped, but it sounds to me like maybe other things are kicked off, or old processes maybe are left over.

Rgrds,
Rita

I don't know why there are 60 but the "D" means the segment is marked for deletion, after all 60 die.

Yes where the "D" is special.

It is the behaviour of EMC CC 6.1. Checkout the following thread:

How can EMC let ecc 6.1 out?
Thanks for the info.
